1. Condition: The condition of the coin is one of the most important factors in determining its value. Coins that are well-preserved and have minimal wear and tear will generally be more valuable than those that are heavily worn or damaged.
2. Rarity: The rarity of the coin also plays a significant role in its value. The 1873 US silver dollar is a relatively rare coin, with a mintage of only 1,500 pieces. This makes it more valuable than more common coins.
3. Mint mark: The mint mark on the coin can also affect its value. The 1873 US silver dollar was minted in two different locations: the Philadelphia Mint and the Carson City Mint. Coins minted in Carson City are generally more valuable than those minted in Philadelphia.
4. Market demand: The market demand for 1873 US silver dollars also influences their value. If there is a high demand for these coins among collectors and investors, their value will be higher.
Overall, the value of an 1873 US silver dollar can range from a few hundred dollars to several thousand dollars, depending on the specific condition, rarity, mint mark, and market demand. To determine the exact value of a specific coin, it is recommended to consult with a professional numismatist or coin dealer who can assess the coin's condition and provide an accurate valuation.
